Yes, but they are only sometimes useful.
Not quite accurate, they're MORE than sometimes useful.
I read them to see where the narsties are and their names. I make notes of them and check to make sure there's no folders on my puter or leftover files.
I agree that they're not always useful as sometimes they are too long to be able to read. I learned to make the Spybot window smaller, drag it to the left and then click the right edge of the window to make it as long as possible.
You can also right-click in the window and "Copy full report to clipboard".
